DUMP-CAR.

Specication of Letters Patent.

Patented Feb. 17, 1920.

Application filed March 23, 1918. Serial No. 224,182.

To all whom t may concern:

Be it known that I, vWILLIAM L. BURNER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

My invention relates to dump cars and comprises means for tripping the lock which maintains the car against involuntary dumping; my lock tripping device is adapted to be actuated from one side of the car to effect an unlocking on the opposite side, and is preferably operated from the power cylinder which dumps the car. It is provided in duplicate preferably one on each side of the longitudinal middle of the car, and the embodiment of my idea herein shown and described includes a bar or rod extending across the car, and this bar comes into activity for tripping the lock when the car bed is being dumped toward the side toward which the bar extends.

In the drawings I show my tripping device adapted to a car having a compression lock member connected with the longitudinal shaft, and having the folding dumping or push members which have been shown in recent applications for patents.

In the drawings which are hereto attached and hereby made a part of this speciiication Figure 1 is a vertical transverse section through the car containing my improvements associated with other operating features of the car; Fig. 2 shows the action of and the positions assumed by the tripping member when the car is dumped toward the side toward which the tripping member extends; Fig. 3 shows the same tripping member when the car bed is dumped in the opposite direction; Fig. 4 shows at the right the positions of the locking parts when normal and when tripped by my improved tripping member; Fig. 5 shows the lock tripping mechanism mounted on the opposite side of thel car from that shown in Fig. 2; Fig. 6 shows the duplicate lock tripping mechanisms, that on the right being in dotted lines to 'indicate a more remote location; F ig.` 7 is an edge View of the strap member adapted to lift the tripping bar.

Referring to the drawings 1 is a car bed pivotally mounted at 2 on the underframe 3`to dump laterally; the cylinder 5 contains the piston Vrod 6 adapted to lift the folding bar member 7 to cause the car bed to be dumped toward the right in the view presented. 8, 8a are longitudinal shafts on opposite sides of the longitudinal axis of the car and as illustrated shaft 8a rigidly carries the slotted member 9 engaging the link 10 pivotally associated with the compression lock bar 11 pivoted to the car bed at 12.

The member 13 rigidly borne on shaft 8il is engaged by the hook end of the tripping bar 141, the shoulder 16 being adapted to exert a push on the rocker arm 13, and the hook 15 being adapted to engage and return said member to normal position when the car bed is righted. The strap 17 depending from the car bed is adapted to lift the tripping bar 14 out of engagement with the rocker arm 13 when the car bed is dumped toward the left as illustrated in Fig. 8.

The tripping bar 14 is pivoted at 18 to a lever 19 pivoted to the car underframe at 20 to swing about said point under the influencey of the said piston rod exerted throu h the pivotal connection therewith at 21 of t e rod 22 pivotally associated with the arm 23 carried loosely on shaft 8 in rigid association with arm 24 pivotally connected by link 25 lwith the piston rod 6 at 26.

In Fig. 1 the car bed is in normal position and all the operating parts are positioned correspondingly. Assume. that the car bed is to be dumped toward the right; the rise of the piston rod 6 to accomplish the tilting of the car bed through the mechanism described above, rotates the lever 19 on its pivot 2O and pushes the tripping member 14 toward the right; the shoulder 16 engages the rocker arm 13 and rotates the shaft, the arm 13 lying in a position practically horizontal at the'end of its travel. The effect of this movement has been to lift the slotted member 9 carrying therewith the link 10 andV consequently pulling the lock bar 11 away inwardly and so permitting the car bed to descend at the right side as shown in Fig. 4.

l similar tripping bar and its associated mechanism are located on the right side of the car as shown in Figs. 5 and 6. to perform the unlocking when the car bed is to be dumped toward the opposite side. Preferably thev mechanisms shown in Fig. 6 are disposed one on one side. the other on the other-side, of the longitudinal center of the car, as there shown but that is a matter of mechanical application dependent upon other features of construction. The duplicate parts are given the same reference numerals with the addition of the prime cha-racter on all the mechanism operable from the right hand side of the car as clearly appears from an inspection of Figs. 5 and 6.

When the car bed is dumped toward the right as shown in Fig. 5, the strap member 17 being drawn up by' the bed in its rotationlifts the bar 14 so that the shoulder 16 islout of engagement with the Vrocker arm 13', while the position of the arm 13 is undisturbed and remains so during the dumping and righting of the car bed, the purpose being to maintain the shaft S in its locking position -until the car bed is to be `dumped toward the left. As the piston rod 6 travels upwardly to lift thecar bed back to normal righted position the bar 111 is thrust laterally, but, as stated, during this thrusting movement is out of engagement with the rocker arm 13. Then -the bar 14 is retracted'by the return of the piston rod 6 to its normalposition, it again rests in normal operating position in the rocker arm 13', since the return of the car bed to normal has also returned the strap 17 to normal position.

It will now be understood that if the car bedbe dumped toward the left, as assumed in Fig. 3, the strap 17 liftsthe tripping bar 14 .outof operating engagement with rocker arm 13, and so maintainsit during the righting process, which will take place bymeans of the movement lof thel piston rod 6. The rise of the piston rod 6 to accomplish the righting of the car bed necessarily thrusts the bar 14 to the right, and when the piston rod descends the bar 14C will be retracted. Meanwhile the strap 17 having Vbeen returned to its normal position by the return of the car bed to normal, the bar 14: will again rest in the strap member 17 as shown in heavy lines in Fig. 3.

Thek construction herein pro-vided for is positive and automatic in its operation, and although susceptible of variations and modifications thek ydrawings show a preferable embodiment thereof.

Whatl claim is 1. In a dump car having a longitudinal shaft disposed on each side thereof, an arm secured on saidshaft, car bed locking devceson eachA side of saidcariadap'ted to be actuated byA the movement of said shaft, a tripping bar mounted on each side of said car and |extending acrosssaid car and engagingsaid arm on said shaft on the opposite side, 4a dumping cylinder on each side of saidcar, means connecting the piston rod of said cylinder-with 'said tripping bar to ro- `tate said shaft onsaid opposite sideand thereby tojunlocl car bed topermit the dumping thereof toward said oppositefside. 2. In a dump car having a longitudinal Vtripping bar mounted on each side of said car and extending across said car and engaging said arm on said shaft on the op-y positeside, a dumping cylinder on each side of said car, 'means connecting the piston rod of each of said cylinders with said appropriate tripping bar to cause the unlocle ing of said carbedon the side thereof opposi'te to said dumping cylinder, the cylinder on lsaidopposit-e side being 4a d'apted to be actuated subsequently to right said car bed, and means adapted Vto lift said tripping bar actuated from said rightingy cylinder out of engagement with said armV on said opposite shaftv to prevent the rotation of said latter shaft out of its locking position during the righting operation. u

3. In a dump car having a longitudinal lock shaft and a dumping 'cylinder mounted on each side thereof, an arm rigidlyv mounted on each of said shafts, a'tripping ybar as-y sociated with and actuated by each of said dumping cylinders adapted to engage the arm on-the opposite side of said carto rotate the shaft on that side when said dumping cylinder is operated to dump said car bed, said other cylinder being adapted for operation subsequently to right said car bed, a strap member depending from said carY bed to engage each of said trippingbarawhereby the tripping bar is lifted awayA fromengagement with the arm on the side of the car bedlifted in the dumping operation and the unlocking ofthe shaftY on vsaid latter side during the subsequent righting -voperation is prevented;

4. In a side dumping ear having at each side thereof a'rdumping cylinder, bed locking means, and a longitudinal shaft, an arm mounted on said shaft,- a member on said shaft 'associated with said locking means to control the same, a tripping bar associated with each of said duinpingeylinders and to prevent unlocking movement of Vsaid 'arinV during theV righting operation.

V5. Ina dump car having a bedmo'unted for dumping 1n both directions and having each aside thereof a llongitudinal shaft 'and a cylmdef fer dumping @fighting said `13o car bed, and car bed locking means adapted to be actuated by said shaft, an arm on said shaft, a tripping bar associated with each cylinder extending across said car and engaging the opposite arm, said. cylinder at one side being adapted to dump said car bed toward the opposite side and at the same time initially to actuate said tripping member to move the opposite arm to rotate the opposite shaft to unlock said car bed on that side, and a strap depending from said car bed for engagement With the said tripping bar which is not utilized during the dumping operation, whereby said bar is lifted out of engagement with the arm by the car bed in its dumping movement and is held out of engagement with said arm While said car bed is being righted.

6. In a car adapted for dumping at both sides, car bed locking means at each side, a cylinder at each side of the car either of which is effective for dumping and the other for righting the car bed, lock tripping means connected with each cylinder to be actuated thereby to release the locking means on the opposite side to permit the car bed to be dumped to that side, and means mounted on the car bed to prevent the tripping means connected With the righting cylinder from tripping the locking means o n the other side during the righting operation.

In testimony whereof I aliX my signature in the presence of two witnesses.
